Click, to see the large size. ▶ BIG FOTO The initial intention behind the Les Cabinotiers Dual moon Grand Complication
watch was to pay an original tribute to the Moon. Often relegated to
the background, the moon display is now very much in the forefront on
this model, asserting its striking presence both by its colour code and
by its size. As the idea was also to offer a vision of the Earth's
satellite as it appears in the northern and southern hemispheres, the
central moon phase indication, already a rarity in the watchmaking
world, is therefore characterized by a double display.

Front: a spectacular show
Indications:
- Off-centre mean solar time with hours and minutes
- Precision moon phases and age in both hemispheres
- Gregorian perpetual calendar with day, month, leap-year indications and instantaneous retrograde date hand
- Minute repeater
- Precision moon phases and age for the Northern and Southern hemispheres
The full measure of Vacheron Constantin's ingenuity in staging the art of watchmaking is stylishly and elegantly expressed in this double-sided watch. This highly complex model is distinguished by the legibility of its hourly and astronomical functions, stemming from the Maison’s characteristic aesthetic quest perpetually focused on essentials.

The semi-instantaneous display of the day and the instantaneous display of the month and leap-year appear through apertures, as does the date display. Here again, this display positioned on the upper rim of the dial is shown through a semi-circular window, but with a retrograde hand. A technical and stylistic signature of Vacheron Constantin since the early 20th century, retrograde mechanisms require great precision in the doubling of the gears used to store the energy required for the return of the indicator.

Back: a cosmic dimension
Indications:
- Tourbillon regulator
- Sky chart
- Sideral hour display
The likewise multi-part rear dial construction ensures the clarity and understatement of the various displays. To ensure the moon phases take priority on the front of the watch, the opening revealing the tourbillon regulator has been placed on the back. Invented at the beginning of the 19th century, this device enclosing the escapement and the balance-and-spring assembly in a mobile carriage is designed to compensate for the effects of Earth’s gravity on the isochronism of the regulator and thus ensure enhanced precision. The one-minute-rotating tourbillon is distinguished by its carriage shaped like Vacheron Constantin’s Maltese cross emblem, with its delicately hand-polished bar. To diminish the weight (hence improving performance) as well as for aesthetic reasons, the tourbillon components have been skeletonised – notably the fixed wheel which is entirely openworked.

Minute repeater
This timepiece featuring 11 of the noblest horological complications laid out in an extremely elegant manner would have been inconceivable without making it a musical watch incorporating a minute repeater.

Calibre 2755 TMRCCQP, a watchmaking adventure
In-house Calibre 2755, one of Vacheron Constantin's major developments, was chosen to power all these functions, which are complemented by a minute repeater chiming the hours, quarters and minutes on demand. This movement has undergone major transformations over the years – notably in the realm of astronomical functions – and represents a true horological adventure.

As is the case with all timepieces from the Maison, this model showcases the extreme attention to detail lavished on every component, even those that remain invisible once the movement has been assembled. This quest for excellence is expressed as much in the technical and aesthetic choices and decisions as in the painstaking finishing.
Summary
